I'm designing a digital clock for a freshman electrical engineering projects course. I am using SN74HC161 4-bit synchronous counter chips for the counting. My design counts seconds and minutes with correct rollovers, and I am going to design the hour logic next.
I am wondering if it is even possible to load values onto my counters as soon as the clock powers up. My counter begins from zero, but I want the clock to default to midnight, for example, because 0 o'clock does not exist. Though I will be adding a feature to set the clock's time (by manually incrementing hours), I don't want my clock to start off with zeros across all my seven segment displays.
This low-res picture is just for a general idea of my design. I am using NI Multisim (and yes, I understand this is a noob-ish piece of software, but I am a freshman electrical engineering student).
Here is a closeup of my counter / decoder chips so you can makeout the pinout.
Any help would be greatly appreciated.
